Application filed September 4, 1926. fierial No. 133,696.

This invention relates generally to grain drills and has more particular reference to a device constructed for disposition upon the seed hopper of any conventional type of grain drill whereby the seed to be subsequently planted by the drill may be properly treated with a suitable chemical so as to prevent smut. The device is also capable of use in the mixing of Various grains, the

or mixing operation being" performed While the drill is being moved through the field, or while the drill is being moved over the field and in the act of planting the previously treated or mixed grain.

The invention further aims to provide a device of this character that is extremely simple of construction and one that may be readily associated with practically all forms of grain drills and this without requiring unusual skill or without in any manner whatever affecting the operation of the drill.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing.

In the accompanying drawing wherein like numerals indicate like parts:

Figure 1 is a front elevation of a conventional grain drill equipped with my improved device.

Figure 2 is a an enlarged detail longitudinal section of one of the drum units of the device.

Figure 3 is an elevation thereof, and

Figure 4 is a detail transverse cross section.

Now having particular reference to the drawing 5 designates generally a conventional form of grain drill that includes a horizontal axle or shaft 6 upon the ends of which are mounted supporting wheels 7-7, said drill also including the usual seed hopper 8 that extends across the entire area of the machine at the rear SldGthGlBOI.

In carrying out my invention I secure to 5 the drill hopper 8 at the opposite ends thereof a pair of vertical brackets 9'9 while at the center of the hopper and upon the top side thereof is a vertical bracket 10 through which is journaled an elongated shaft 11 upon one end of which is a sprocket gear over which is trained a sprocket chain 12 the same being extended downwardly and in turn trained over a sprocket gear upon the ad acent end of the drill axle or shaft 6. The

sprocket gear upon the end of the shaft 11 is loose thereon and is formed at its inner side with a clutch face 13. 1s a clutch collar 14 operable into or out of engagement with the clutch face of said shaft sprocket gear by reason of a suitable lever 15. This construction is'provided in order that the operation of the shaft 11 may be cut out whenever desired.

Mounted upon said shaft 11 are a pair of elongated drums 16-16 spaced a slight distance apart at their inner ends as indicated in Figure 1 Each drum 16 is provided at its center with a partition plate 17 so as to divide the drum into a pair of compartments, each of which is formed with an opening 18 normally maintained closed by reason of a shding door 19. Directly opposite each opening of the drum the wall thereof is formed with a short discharge nozzle 20 with which is associated a valve plate 21. These nozzles v are provided in order that treated or mixed grain may be properly drawn from the drum compartment and passed into the hopper of another grain drill not equipped with my device or to suitable storage pit. It is of course to be understood that when the seed is withdrawn from the drum it is necessary that the drums be turned so that the nozzles will be at the bottom side thereof.-

Arranged within the compartment of each drum 16 is a diagonally extending V-shaped bar 22, the inner end of which crosses the shaft 11 and projects a slight distance through the partition wall 17 into the next compartment. These bars are provided in order that when the drums are being rotated, some of the seed will be caught therein when Splined upon the shaft the bars are at the lower side of the drum so a that during the further rotation of the drum the seed willjbe caused to move horizontally within the drum and passed from one compartment to another. bars the seed within the drum is thoroughly agitated as-to facilitate the proper mixing of the same.

It will thus be seen that I have provided a highly novel, simple, and eflicient form of seed cleaning and mixing device for grain drills that is well adapted for all the purposes heretofore designated and even though I have herein shown and described the invention as consistingof certain detail structural elements it is nevertheless to be understood By reason of these 7 that some changes may be made therein Without affecting the spirit and scope of the appended Claim. 7

' Having thus described the invention, What 5 I claim is 2- A seed treating and mixing device consistmg of a rotary drum; a partltlon transversely V of the drum to divide the same into a pan of compartments, and channelled bars one extending diagonally in each compartment and through the partition so that upon rotation of the drum, the contents of one compartment may move along the channel bars therein into the other compartment.

In testimony whereof I affix my signature.
